For the sparing mode, please follow the online spare FBDIMM configuration requirements (in addition
to general configuration requirements) below:
•
When only DIMM1&DIMM3 are being used, they must be fully populated with dual-rank
FBDIMMs.
•
If DIMM1&DIMM3 and DIMM2&DIMM4 are being used, they must be fully populated.
•
If installed, DIMM1&DIMM3 and DIMM2&DIMM4 must contain FBDIMMs with identical part
numbers.
•
If installed, DIMM5&DIMM7 and DIMM6&DIMM8 must also contain FBDIMMs with identical
part numbers.
In the online spare mode, FBDIMMs must be populated as specified in the following table:
